Isotopes of hydrogen

Hydrogen (H) (relative atomic mass: 1.00794) has three naturally occurring isotopes, sometimes denoted 1H, 2H, and 3H. The first two of these are stable while 3H has a half-life of 12.32 years. All heavier isotopes are synthetic and have a half-life less than one zeptosecond (10−21 second). Of these, 5H is the most stable, and 7H is the least.

Hydrogen is the only element whose isotopes have different names that are in common use today. The 2H (or hydrogen-2) isotope is usually called deuterium, while the 3H (or hydrogen-3) isotope is usually called tritium. The symbols D and T (instead of 2H and 3H) are sometimes used for deuterium and tritium. The IUPAC states in the 2005 Red Book that while the use of D and T is common, it is not preferred because it can cause problems in the alphabetic sorting of chemical formulae. The ordinary isotope of hydrogen, with no neutrons, is sometimes called "protium". (During the early study of radioactivity, some other heavy radioactive isotopes were given names, but such names are rarely used today.)

GM HydroGen4

HydroGen4is the successor of the fuel cell vehicle HydroGen3, developed by General Motors/Opel and presented in 2007 at the IAA in Frankfurt. It is expected that automotive hydrogen technology, such as the type featured in the HydroGen4, may enter the early commercialization phase in the 2015 - 2020 time frame.

Specification

The vehicle is based on the Chevrolet Equinox and has a GM fuel cell with 440 cells and an output of 93kW. The hybrid powertrain also contains a nickel-metal-hydride battery with an energy content of 1.8 kWh/35kW and a three-phase synchronous motor with 73kW continuous power and 320 Nm of torque. The peak power of the engine is 94kW. The hydrogen tanks at 700 Bar (10000 PSI) pressure contain 4.2 kilograms of hydrogen, which last about 320 kilometers (200mi). The maximum speed is 160km/h with an acceleration from 0 to 100km/h in 12 seconds. The HydroGen4 is produced in a batch of 170 pcs from which 10 for the Clean Energy Partnership project in Berlin.

Memory

In psychology, memory is the process in which information is encoded, stored, and retrieved. Encoding allows information from the outside world to be sensed in the form of chemical and physical stimuli. In the first stage the information must be changed so that it may be put into the encoding process. Storage is the second memory stage or process. This entails that information is maintained over short periods of time. Finally the third process is the retrieval of information that has been stored. Such information must be located and returned to the consciousness. Some retrieval attempts may be effortless due to the type of information, and other attempts to remember stored information may be more demanding for various reasons.

From an information processing perspective there are three main stages in the formation and retrieval of memory:

Encoding or registration: receiving, processing and combining of received information

Storage: creation of a permanent record of the encoded information in short term or long term memory

Memory (2008 film)

Plot

Krit, a married psychiatrist in Chiang Mai, is tasked with looking in on Phrae, an abused, 7-year-old girl. Her mother, Ing-orn, cannot explain the bruises on the girl's body. As he participates in the case, Krit finds himself falling in love with Ing-orn.

Memory (2006 film)

Plot

While lecturing in Brazil, Dr. Taylor Briggs an American authority on memory consults on a patient found deep in the Amazon. During the exam, Taylor is accidentally exposed to a mysterious substance which unlocks a series of memories in his brain. Memories that are not his. The memory of a killer who committed crimes before Taylor was even born. A killer who is much closer than you may think.

The mystery will rip open Taylor Brigg’s well crafted life, estranging his relationship with his best friend Dr. Deepra Chang, leading him into romance with a beautiful, enigmatic painter Stephanie Jacobs, straining his relationship with his mom’s best friend Carol Hargrave, causing him to question the surrogate father figure in his life, Dr. Max Lichtenstein.
